$30-250 USD

Paid on delivery
I have developed a database of a food delivery mobile app. The database schema contains circles, which is not right on database schema design. I need someone to review the database schema design & planning, validates it against normalization, naming standards and modify the schema. Business Restaurants add their products in the products table. Each product has extras associated to it, e.g. Burger has ketchup and chees as extras. Clients filters out restaurants and meals. Then they chose a product and the desired extras and put on the basket.
